A network design must meet the increasingly complex requirements of the organization that it supports. As a network designer, you should understand the needs of the organization and follow a methodology that helps match needs to the network implementation. In the current business climate, organizations are looking for ways to enhance customer relationships, accommodate a mobile workforce, and increase productivity. In addition, companies are looking for ways to integrate emerging technologies like wireless, virtualization, video, unified communications, and a vast number of application-level business solutions into their enterprise. These challenges create the need for a more flexible and dynamic network architecture. This course introduces principles and guidelines for building an effective network design that addresses such challenges.
The course begins with an overview of the Cisco Network Architecture for the Enterprise, which enables customers to build a more intelligent infrastructure. The course also describes how to gather customer requirements and identify business and technical constraints using the Cisco Lifecycle Services process. Because many customers build on an existing network, the module also presents methods of characterizing the existing network. The course concludes with a discussion of the design implementation process, including prototypes, actual implementation, and verification of the design solution.
